Application and June 17. 1907.

T 0 all whom it may concern;

Be it known the" i1, DALTON K.WILSON, a citizen of the UL. States of America, and a resident of Vt 'aterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Man urefip'readers, of -which the following is a specification.

My invention relates to improvements in manure spreaders, and the object of my improvementis to provide an improved ratchet drive the movable apron such device being furnished with means for varying the speed. of the apron relative to the advance of the machine. This object I. have attained by the mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawings, in which Figure l is a side elevation of the wagon box of a manure s urea-tier supplied with my improved ratchet-driving device. Fig. 2 is a detail plan'view of a part of such device.

Similar reference numerals refer to similar parts throughout the several views.

The wagon-box 28 is supplied at its rear end with a bracket 26 on each side, which supports therotatable shaft 25 on which is fixed the beater-drum 14. An endless apron 21 is mounted in said box 28 to move about front and rear sprocket-wheels, the rear sprockets (not shown). being secured to a transverse shaft 10, on one end of which is secured a large ratchet-wheel 1. A camwheel 8 is secured to the shaft 25 on the same side oi the box as the ratchet-wlwel 1, and is ada )ted to drive said ratchebwheel by means of the 'lollowing described connections and moving and contactin v elements. A lever composed of two para lel side-bars 2-2 is pivoted near one end on a'stud 17 project ing outwardly from the forward upper corner of the bracket 26. The upper portionof the rear end of said lever 2-2 is beveled and covered over by a ooi'itactepl'ate 9, and the plate 9 is contacted by the cam-wheel 8 to impart a swinging up and down movement to the said lever. The weight 30 secured to the forward end of the lever 2 2 keeps the rear end of the lever normally in: operative contact with the edge of the cam-wheel 8. The space between the side-bars 2 .2 is open forward of the plate 9, and in that space a pawl 11 pivoted on a rod 7 extending from one bar 2 to the other. In the inward art of such space another pawl 15 is pivoted on the stud Specification of Letters Patent.

17. The pawl 11 base depending projection. .20, and the pawl 15 has an upper arm 18, and between the projection 20 and the arm 18 a coiled tension spring it) is connected. A lever 12 has itslower end pivoted on the stud 17, while to its upper endis pivoted the rear end of the *o!11ieciingr0d 6 on a stud 13. The lever 12 and the pawl 15 are secured together and acttogcther pivotally upon the stud 17. The pawls 11 and 15 are adapted to res )ectivcly engage the teeth of the ratchetwheei 1. I

The forward end of the lever 2 has an upward projectirm. formed of two uprights connected by a face-plate 3 which has a been ing-oriiice near its upper end. The connect-- ing-rod 6 is slidable within the orilicc in. the plate A short distance anterior to the plate I} a ring or lug 27 is secured tothe rod 6, and a coiled compression spring euc-irclw said rod between said lug and plate. The 5 extending trom rod 6 is slidablc in an ear the outer side of the box 38, the forward end of said Ted being n'iountcd in a swivelbearing 22 connected to the hand-lever 2.3 at a point intermediate between its ends. The lower end of the handdcver 23 is pivoted to the forward part of the box while-its upper end engages a rack-bar 2%. whereby it may be set or adjusted at desired distance forward or back.

When the beater-drum-chaft 2.5 is rotated, the cam-wheel 8 imparts a swinging movcment to the lever 2---Z, and the pawl H drives the ratchet-wheel 1. through the space of a certain number of teeth, such number being determined by the udiustmcut oi the lever 23 in its inch-bar 24; \Yhcu the lever 23 is moved back its action is to cause through spring 4 the lever J-----2 to lower wit h its pawls ll and l5,which diminishes the amplitude oi' movement of said parts and permits the ratchet-wheel to be moved over 51 space of a lesser number ol teeth. 'liuthrowing forward of the hand-lcvcr allows the lever 2--2 and pawls to lift, and acct-lorate the movement of the apron by movi up; i he pawls over a s iace of a greater mmihcr of teeth, and when the lever is throu u barlv ward to the extreme position said lever 22 is held down from the am-wheel which .aps the movement of the apron. when the lever 2-2 lowers, the pawl elicits over 1 the teeth of the. ratchet-wheel as the pawl 11 drives the latter. the spring-councition it keeping both pawls always in contact with said ratchet-wheel. When the lever 22 rises the pawl 15 holds said wheel while the pawl 11 1s clicking over it. The spring 4 forms a resilient'connection between the rod.
